Not sure why you be interested but here goes.
I am self employed I have my own Pet sitting business that is doing extremely well because of my business model and the wonders of the internet and Live feeds to owners to see their dogs on holiday. 60% English speaking of many countries and around 40% french nationals (many of those also speak english but not all)
Defo full time its a 7 day a week job (i love it ) 7am to 10 or 11pm and even then the dogs are with me all night too.
Before i moved to france i worked in Mental health and before that I was a tech manager.
No multiple jobs as no time.
Not a pensioner.
